swing barrel fix?
« on: July 02, 2018, 05:53:21 PM »
Getting ready for firewood cutting this winter :)

On my old what I believe to be a Barko 80 log loader with swing barrels, the internal seals are shot from what I can tell. Has power to turn l & r but wont stay put if I leave the valve in center. Could be the valve body I guess too, but the rest of the cylinders on it are fine.

The barrels are screw in, and just wondering  what would be the best tool to turn them off? It looks well oiled at the threads from years of minor fluid leaks. Giant pipe wrench? Other ideas?

Large chain wrench would be my first choice.

Which brings up, what is a quick way to tell whether its a valve or cylinder that's leaking down?

A swing barrel is a one way cylinder, if the packing is leaking, oil will run out the open end.

not sure where I can get a chain wrench that is big and heavy enough. Have a 24" but I consider it to be light duty. Did nothing on the cylinder. Thoughts about welding a 3" (head size) nut onto the end of the cylinder with the hose off? I have a socket that size with a 1" breaker bar.....

Check if that has a clamp bolt on the mast were the barrel threads in. If'n I member right, the Prentice I had, had a bolt that clamped the threads tight to the barrel once you assembled it.

i have actually welded a piece of 3/4 x 3 flat bar about 6 feet long, right to the end cap.  worked awesome as a breaker bar and once turning free you just cut it off.  If i remember correctly, ours had a clamp setup near the threaded end.

I emailed Barko and then spoke on the phone. They were super helpful. Not 100% sure mine is a Barko but there is a nut that I can actually undo a bit that locks things together. Inside looks like a simple fix once I get it apart. Stay tuned......will try to hammer that nut loose before I go build myself a wrench to turn it.

Reckon if you put the hot wrench to it for a bit thatll turn via chisel and hammer if youve got the room.  Big channel locks?

I was planning on tearing into this tomorrow aft but now that I think about it, I am going to do the control valve first. I assumed there was a seal on the end of the tube itself, but the piston bolts directly on to the end of the rack. If it was leaking at the piston seals like I thought it was, there would be fluid all over the ground. It is sloppy as heck. The whole rack is not a sealed mechanism. Good news is the rack and associated turning gear look to be in excellent shape.

First will be the valve and then will go from there. Will try and make a before and after video!

I'm wearing my "Slow Children" T shirt here.
So as a basic order of troubleshooting, if a double acting cylinder is drifting, unless there is fluid coming out of the cylinder or other external leak, check the valves first?

Never saw one like that. My Barko 80 swing barrel had an acme thread and a clamp ring.

It may not be a Barko for real but close I figure. The first couple years of a Barko 80 had a threaded ring much like the nut in my photo. No hex to grip on to but also no bolt to release it. According to their parts diagram anyways. Everything else looks the same.

Am eating some humbleberry pie for dessert. Took the spool valve apart and there were no orings left at all on the shaft.

My big sister always threatened to get me one of those shirts :)

Don't stop taking pictures, I think there's 7 slices of that pie in my future ;D

That does look like Barko orange under that yellow paint.

I think there was also a loader called Husky or Husky Brute that looked a lot like a Barko. I've never actually seen one, only on the interweb.

Mike, I would disagree with your answer, if a double acting cylinder is drifting the oil should return to the tank, as per the link you posted above.

A swing barrel is a single acting cylinder and if the seals on the piston leak, the oil should run out the open end.

Thanks for putting up that link, I found it quite interesting.
